Non-Working Drivers

Many drivers in MAME are tagged as non-working. In many cases it is obvious why the drivers don't work. In some cases it is subtle. And quite often, other devs can't even really remember why some games don't work. This section of the wiki is an attempt to provide some additional information that can be widely shared about why the games don't work. Hopefully it will answer some of the many questions out there, and might even encourage others to help complete the driver.

These are grouped in several categories based on the game flags in the drivers:

• GNW - GAME_NOT_WORKING
• GUP - GAME_UNEMULATED_PROTECTION
• GNS - GAME_NO_SOUND and GAME_IMPERFECT_SOUND
• GIG - GAME_IMPERFECT_GRAPHICS. Also covers GAME_IMPERFECT_COLORS and GAME_WRONG_COLORS

The old list is below. All of this should already have been merged into the above lists and will eventually be removed.

• Jaleco
• Kaneko
• Konami
• Midway
• Other
• Psikyo
• Sega
• Seibu
• Stern
• Tecmo
